European Perch from Spain, Embalse de Mequinenza

I was fishing for Walleye in Spain, Embalse de Mequinenza, when my softplastic minnow was attacked. Sure of another walleye I did not expect a different species to strike. Finally I saw this 38 cm European Perch and luckily could land it. The fish was round and healthy so it could be released quickly after this photo.
